Found 4 hours between 8pm and midnight on Friday to work on the car. Saturday was spent mostly doing housework (mowing) and getting the F500 ready for Sunday. Sunday was spent autocrossing. First autocross was 35F and pouring. Second (yesterday) was 90F and humid. I wouldn't mind averaging those out a little. Got FTD and 6th on PAX.
I made some spacers for the seat mounting and sub harness. I didn't like bolting through thin walled tubing knowing it was holding me in. The bottom of the tube is drilled for the bolt through hole, the top was drilled for the spacer to drop in. Spacer was .050" below the top of the tube to make sure that there was melted material below the top surface of the tube. I TIG welded them and then, where needed, ground the top flat so I wouldn't be putting excess stress on the seat mounts. Having spent 95% of my time welding aluminum, welding steel was a nice surprise at how easy it felt.
No pics for this part, but I also finished mounting the fuel tank and the lower firewall. The new tank is stiff and pulled the floor of the car flat so the holes for the lower firewall didn't like up anymore. Ha!
